然后执行yum clean all和yum makecache，待执行完成后即可正常使用yum。

解决configure报错

运行./configure报错一般可能是缺少C/C++环境，执行yum install -y gcc-c++即可。

编译安装MySQL时报错

编译安装MySQL时出现：

checking for termcap functions library… configure: error: No curses/termca

解决方法：执行下列代码

yum list|grep ncurses
yum -y install ncurses-devel
yum install ncurses-devel

然后重新执行./configure即可。
